Final answer:
Night terrors are a sleep disorder where the individual experiences panic and might scream or attempt to escape, typically during the NREM sleep phase, and usually do not recall the event afterwards.
Step-by-step explanation:
Night terrors can be distinguished from nightmares in that night terrors are a sleep disorder characterized by a sense of panic, often involving screams and attempts to escape the immediate environment. Unlike nightmares, during night terrors, a person may seem to be awake, but they typically have no memory of the event and are not responsive to consoling. Night terrors occur during the NREM phase of sleep, and most individuals fall back asleep shortly after an episode. Treatment for night terrors is not usually required unless they are caused by an underlying condition.
